Meeker, Troy, Ohio, assignors to The Hobart Manufacturing Company, Troy, Ohio, a corporation of Ohio Filed Nov. 13, 1958, Ser. No. 773,599 3 Claims. (Cl. 137-35517) This invention relates to dishwashers, and more particularly to portable dishwashers for domestic use of the type adapted to be detachably connected to a water supply and drain for use.

It is a primary object of the present invention to pro vide a portable dishwasher of improved and novel construction which is characterized by ease of use and efficiency of operation, and which also is wholly automatic in operation.

Still further objects of the invention will be apparent from the following description, the accompanying drawings and the appended claims.

FIG. 13 is a fragmentary View similar to FIG. 8 but with the cover opened; and

FIG. 14 is an exploded perspective View illustrating component parts of the latch mechanism.

Referring to the drawings, which illustrate a preferred embodiment of the invention, the dishwasher includes an outer cabinet shell 15 and a bottom structure 16 which is supported on four casters '17 for free portability. Within the cabinet 15 is a generally rectangular tank 20 which defines the washing chamber, and the tank '20 inice cludes a depending sump portion 21 which is covered by a screen assembly comprising a fine screen 22 and removable coarse screen 23 shown as of the same construction disclosed in the copending application of Geiger et al. Serial No. 529,489, filed August 19, 1955, now Patent No. 2,862,510 and assigned to the same assignee as this application. The sump 21 also houses the pump 25 for circulating the wash and rinse water through the washing chamber by means of the rotating wash arm 26, and the drive motor 27 for the pump 25 depends from the sump 21, all also as described in the above application.

Since the dishwasher is of the portable type, it is provided with an access opening at the top for loading and unloading the articles to be washed. A top cover 30 is mounted at the back of the cabinet for hinged movement between open and closed positions as shown particularly in FIGS. 11 and 12. In addition, means are provided for circulating heated air through the washing chamber at the end of the washing cycle to dry the washed articles. As shown particularly in FIGS. 4 and 7, a heater unit indicated as a cone type electric heater 33 is mounted in a housing 35 in the lower part of the cabinet 15, and a flow of air over this heater is provided by a fan 36 driven by an electric motor 37. The air to be heated enters through slots in the forward end of the housing 35, and the heated air is introduced into the interior of the tank 20 through a duct 40 which extends upwardly along the back of the tank and connects with the interior of the washing chamber through an inlet passage 41.

The successive steps in the washing and drying cycle are controlled by a sequence timer indicated generally at 44 as mounted in the front of the cabinet and provided with a dial 45. The arrangement in this respect and the sequence of operation may be as disclosed in Geiger et al. Patent No. 2,707,961 issued May 10, 1955 to the assignee of this application. Initiation of the cycle may also be effected as described in that patent, through a push rod 46 which extends upwardly behind the front of the cabinet 15 through a guide bracket 46a and is connected by a slide plate 49 with an actuating button 47 mounted for Vertical sliding movement on the trim plate 48 on the front of the cabinet.

The construction and arrangement of racks for supporting the articles to be washed within the washing chamber is best shown in FIGS. 2, 4 and 6. The lower rack is indicated generally at St}, aind it includes a main framework of wires 51 arranged in a horizontal plane in combination with upright supporting fingers 52 for plates and dishes. This lower rack 5d may readily be formed of heavy wire, preferably coated with rubber or plastic to cushion the dishes, and downward extensions 53 at either side of the framework 51 straddle the wash arm 25 and seat on the bottom of the tank as shown in FIG. 6. A wire basket 55 for silverware is supported on one end of the rack 5d, and it will be noted in FIG. 2 that the framework 51 is interrupted at 56 below the basket 55 so that when this basket is removed, as illustrated in FIG. 2, free access is available to the sump for removal of the coarse strainer 23 without the necessity of lifting the rack itself.

The upper rack means comprises three separate rack members, a center rack 6t} and a pair of side racks 61 and 62, the relative widths of these racks being such that the central rack is somewhat more than half as wide as the interior of the tank 20. Each of these upper racks 596@ is suspended Within the upper part of the washing chamber by hanger portions 63 which are turned outwardly at 64 at their outer ends to hook over a peripheral ledge 65 which runs around the entire top of the tank. The central rack may advantageously be fitted with a screen cup for detergent, as indicated at 66 in FIG. 2.

The upper racks 6ii-62 and the tank 20 are especially proportioned in such manner that the central upper rack 65 can be supported at the top of the tank to leave access therepast and between the two side racks 61 and 62 for loading and unloading the lower rack 50. Thus as shown in FIG. 4, when any of the upper racks is suspended in operating position, it fits between the front and back of the tank 21?. However, this dimension of the tank is longer than its width by an amount approximately equal to twice the width of the ledge 65, or similarly equal to the total dimensions of the hanger portions 64 of one of the racks eeez, so that the central rack so can be withdrawn from the tank, rotated through 90 in a horizontal plane, and then set at the back of the tank on opposed side portions of the ledge s5. When the racks are in these relative positions as shown in FIG. 2, there is free access past the central rack 6t? and between the side racks 61 and 62 to the entire supporting area of the lower rack th for loading and unloading the dishes or other articles to be washed.

Since this dishwasher is of the portable type, it is provided with a detachable connection to a water supply, and this connection also includes means for draining the tank after each washing or rinsing operation is completed. Referring particularly to FIGS. 2, 4 and 7, the water supply hose 7t) and drain hose 71 are both connected to an adapter 72 of a conventional type constructed for attachment to a water faucet 73 as shown in FIG. 2', and which includes provision for directing incoming hot water to the supply hose 7t} and for draining through its lower end the water supplied thereto from the drain hose '71.

The supply hose 7% is connected at '74- within the back of the cabinet with the solenoid operated fill valve '75, which is mounted on a channel member 7s extending across the back of the cabinet. When this valve '75 is open, its outlet '77 discharges across an air gap serving as a suction breaker into a fixture '78 which leads through the back of the tank 2% and in turn discharges against a deflector '79 for the purpose of causing the incoming water to spray over the dishes as it enters the tank. This water accumulates in the sump 21 for subsequent circulation by the pump 25 through the wash arm 26 as described in the above Geiger et al. application Serial No. 529,489, now Patent No. 2,862,510. At the end of each washing and rinsing step, the liquid is drained from the sump 21 by a drain valve assembly Stl which is also shown as of the construction disclosed in application Serial No. 529,489, new latent No. 2,862,510 and includes an operating solenoid as indicated at 31.

The outlet connection from the drain valve 83* leads through a trap 82 to the drain pump 33, which is mounted directly below the motor 27 for operation thereby, and which therefore operates whenever the motor 27 is running but pumps only when drain valve 36 is open. A hose 84 leads from the drain pump 83 as indicated in PEG. 7 to a U-tube 35 whicn forms a part of a bracket 86 mounted on the channel member 76 and the drain hose 71 is attached to the opposite end of this U-tube S5. The other hose 37 shown in FIG. 7 is the breather tube from the trap 82, and it connects with an extension d8 attached as shown to the back of the cabinet and terminating just below the top of the cabinet. Access to these parts is afforded by a removable back cover 9% which projects beyond the outline of the cabinet 15 and is provided with a trim cover 91 at its upper end.

The free ends of the hoses 70 and 71 extend through a passage 92 in the trim cover 91 and are received in a compartment 93 defined within the back cover irl by a panel 94, and the hoses 7n and 71 depend in a single loop in the compartment )3 when the dishwasher is not in use, at which time the adapter 72 rests in tl e recessed back portion of the trim cover 91. A curved bracket 95 projects across the compartment 93 from the top of the panel )4 at a position below the till valve 75 and the U- tube 55, and the portions of the hoses id and 71 between their secured ends and the passage 92 are looped around this bracket 95 for engagement therewith preventing possible kinking of the hoses when they are withdrawn to the maximum extent from inside the cabinet. In addition, since the U-tube is positioned in forwardly spaced re lation with the connection 74 between the fill valve 75 and the hose 79 as shown in FIG. 7, the two hoses 7d and 71 fall into natural loops in side by side relation when they are returned to the compartment d3 with minimum possibility of tangling, and this result is also aided by the guiding action of the bracket 25.

Special provision is made in accordance with the invention for the disposal of the electrical supply cord 99 for the motor and other electrical equipment within the cabinet 15. The free end of the cord 99 carries a plug 100 for attachment to a suitable wall receptacle, and when the diswasher is not in use, this plug is supported similarly to the adapter 72 in the trim cover 91. The inner end of the cord 99 extend through a relatively stiff coil spring 101 which is located adjacent one rear corner of the cabinet and is secured to the bottom of the cabinet by a clip or clamp 102 in such manner that it normally tends to extend forwardly along the bottom of the cabinet in generally parallel relation with the side of the cabinet in the compartment 103 defined by the side wall of the cabinet and a guide baffie 104 which extends between the corner of tank 20 and the bottom of the cabinet. In addition, the cord 99 passes through a tubular guide 105 which is secured to or a part of the bracket 86, and which is arranged with its lower portion projecting laterally and forwardly intothe compartment 103.

The result of this arrangement is that when the cord 99 is pulled out of the cabinet for use, it will tend to lift the spring 101 as shown in dotted line in FIG. 3. However, when the cord is disconnected and pushed back into the interior of the cabinet, the shape and position of the guide 105 will tend to direct the central portion of the cord forwardly into the upper part of the compartment 103. At the same time, the natural force of the spring 10 1 in returning to its normal fiat position shown in full lines in FIG. 3 will direct this slack central portion of the wire into an enlarged loop lying along the side of the cabinet instead of permitting the wire to assume some other irregular configuration which might tend to cause it to kink when it is again withdrawn for use. This arrangement of the guide and spring has been found to be particularly useful in making it easy for the user to return the cord to the interior of the cabinet while providing maximum protection against kinking or tangling of the cord.

As already described, provision is made in accordance with the invention for circulating heated air through the washing chamber at the end of the washing cycle to dry the washed articles, and preferred results with this arrangement are obtained by providing also a vent for such heated air while at the same time preventing the possibility of discharge of liquid through such vent. This result is obtained in accordance with the invention by a special structural arrangement in the top cover 30 for the cabinet, and it is shown in detail in FIGS. 8 and 9.

The cover 30 is formed near its front edge with a recess 110, and a slot 111 is provided in the front of this recess and forms the vent outlet. In order to prevent the possibility of water being splashed directly out through the slot 111, a baffle plate 112 is mounted to overlie the major part of the recess 111), and this bafiie plate is clamped between the cover 30 and a trim bracket 115 which is screwed to the cover and incorporates a grill construction 1116 through which the heated air can escape from the washing chamber after passing around the back edge of the bafiie plate 112.

It will be apparent that some water may reach the underside of the b aille plate 112, either by being splashed out from the interior of the washing chamber or as condensate from the heated air during the drying cycle. In order to prevent any possibility of outward discharge of such liquid, the baffle plate 112 is formed in a fiat V- shape as best seen in FIG. 9 such that its rearward edge projects below the level of the major portion of the cover. Any water collecting on the underside of this battle will therefore tend to drip back into the recess 1'10, and this recess is therefore similarly formed in a flat V-shape sloping toward the front of the tank provided with a drain opening 117 at its lowest point through which any such accumulated liquid can drain back to the interior of the tank.

The trim bracket 115 also supports a portion of the novel latch mechanism for the cover 30, which is carried by an additional bracket 120 mounted in depending rela--- tion on the front edge of the trim bracket115. The latch handle 121 includes a shaft portion 122 mounted for rotational movement in the bracket 120, and this shaft portion carries the latch 123, which is of generally hook shape and is adapted to engage under a roller 124 on a stud 125 extending through the trim plate 48. This stud 125 is mounted on a bracket 126 which is in turn secured by screws 127 and a tapping plate 127a to a bracket 128 welded on the front of the tank 20 as best seen in FIG. 14, and it will be noted that the bracket 126 is slotted at 129 to receive the mounting screws 127 for adjustment purposes in assembling the parts as described hereinafter. A keeper 130 is mounted on the stud 125 and is slotted at 131 on its under side to provide for direct engagement between the latch 123 and roller 124. The keeper 130 is prevented from rotation on stud 125 by means of a dowel pin 132 on its inner end which is received in a hole 133 in the bracket 126.

In assembling these parts, the cover 30 is held tightly closed in latched position, and the bracket 126 is pulled down as far as possible to maintain the cover tightly closed, after which the mounting screws 127 for the bracket 126 are tightened, with the slots 129 thus compensating for such misalignments as may have occurred between the tank and the cabinet and thereby assuring tightly sealed closing of the cover in use. Thereafter the trim plate 48 is mounted in place by the screws 134 which thread into the bracket 126, and it will be noted that these screws 134 pass through slots 13 4a in the trim plate 48 which provide for adjustment of the trim plate to the proper position on the front of the cabinet in all adjusted positions of the bracket 126, and which are concealed by the large heads of the screws 134. The trim plate 48 is similarly slotted at 134b for adjustably receiving the pin 134 when the keeper 131) is then mounted in place.

The bracket 126 also provides a mounting for a switch 135 which corresponds to the switch 110 in the above Geiger et al. Patent 2,707,961 and is connected to interrupt operation of the timer 44 unless it is operated by a cam portion 136 of the latch 123. As best seen in FIG. 8, the operating button 137 for the switch 135 projects through the trim plate 48 below the stud 125 but shielded by a skirt portion 138 of the keeper 130, and it is operated by the cam 136 only when the latch 123 is in fully latched position. In this way, positive provision is made that the dishwasher will not operate unless the cover 30 is closed and the handle 121 is fully latched, and provision is also made by the invention for moving the handle to its release position if the cover should be closed while the handle is in its latching position. It will also be apparent, as best shown in FIG. 13, that this latch construction has no vertically open slot or aperture through which liquid or solid particles of food or foreign matter could drop into the interior of the latch or switch mechanism when the cover is open. In addition, with the switch button 137 shielded by the skirt 138 as best seen in FIG. 13, the switch 135 is positively protected against accidental operation.

Referring particularly to FIGS. 9 and 10, the latching and release positions of the handle are established by a studportion 140 of the trim bracket 120 which projects rearwardly from the bracket into an arcuate slot 141 in the latch 123. A loop spring 142 is secured at its opposite ends to the latch 123 and to a screw 143 on the bracket in such manner as to provide an overcenter action urging the handle at all times toward the nearer of its two limit positions. Therefore, if the cover is closed with the handle biased to its release position by spring 142 as shown in FIG. 10, the lower end of the latch 123 will clear the keeper to permit closing of the cover, after which the handle must be manually shifted to its latching position shown in FIG. 9, and while this is done, the cam 136 will operate the switch button 137.

If it is attempted to close the cover 30 with the handle 121 in is latching position, the lower end of the latch 123 will first engage a sloping cam surface 145 on the keeper 130 above the roller 124, and this will shift the handle, with the aid of the spring 142, to its release position permitting the cover to be closed. It will still be necessary, however, thereafter to latch the handle manually before the dishwasher can be turned on, or before the washing action can be continued if the cover was open during the washing cycle to remove or replace one or more articles.

Special provision is also made by the invention not only for sealing against the possible escape of liquid between the cover 30 and the top of the cabinet 15 but also for assuring that any water drops which may have accumulated on the underside of the cover will drain into the interior of the tank when the cover is opened and cannot escape to the floor. Referring particularly to FIGS. 11 and 12, the top edge of the cabinet is enclosed by a sealing strip which in section has roughly the outline of the letter F. The flange portion 151 of this sealing strip is received between overlapping flange portions of the tank 20 and the cabinet shell 15 and is secured therebetween by screws 152. The upper flange portion 155 of the sealing strip 150 is of cored construction for ready compressibility, and its upper surface 156 slopes downwardly and inwardly toward the tank 20.

The cover 30 is of smaller lateral dimensions than the cabinet 15, and it is mounted in such manner that in closed position, it will fit within the outline of the cabinet and set on the sloping upper surface 156 of the sealing strip 150. Thus as best seen in FIG. 11, the hinged mounting of the cover 30 includes hinge members 161) which are screwed to the channel member 76 and are connected by pivot pins 161 to hinge members 162 which overlie the back of the cover 30 and are mounted thereon by screws 163. These hinge members 162 include extensions 165 at the back which are connected to counterbalancing springs 166, and the lower end of springs 166 are in turn connected by adjusting brackets 167 to the lower ends of the hinge members 160. In addition, the extensions 165 includes stop 168 which abut the central web portions of the hinge members 161] to establish the maximum open position of the cover.

The cover 36 is bordered by a sealing strip 170 which includes a lower portion 171 of cored construction for compression into sealing relation with the cored flange portion 155 of the sealing strip 151 in the closed position of the cover 30 as shown in FIG. 11. In addition, the outer edge flange 172 of the sealing strip 170 is formed to incline forwardly and downwardly when the cover is raised to its maximum open position as shown in FIG. 12. The result of this construction and arrangement is that any water drops which may have accumulated on the inner surface of the cover are free to run down toward the back of the dishwasher until they reach the edge 173 of the flange 172, but this is the lowermost part of the cover, and since it lies above the inwardly sloping surface 156 of the sealing flange 155, such Water cannot run beyond the confines of the tank but instead must drop onto the surface 156 and then run back into the interior of the washing chamber, as indicated at 175 in FIG. 12.

This invention therefore provides a dishwasher having a variety of outstanding practical advantages. Thus while the dishwasher is of the top opening construction which is convenient for a portable unit, it incorporates means for circulating heated air through the washing chamber to dry the dishes without requiring that the top be opened during the drying operation, and the top can therefore be kept closed for possible use as a work surface at all times except when the unit is actually being loaded or unloaded. At the same time, the invention provides positive assurance against leakage of liquid from the interior of the washing chamber, either through the hot air vent, or by drainage from the cover during times when the cover has been opened, such particularly as when it is opened during the washing operation to insert additional dishes. Another advantage related to the top opening construction of the dishwasher is the individual structure and arrangement of the racks, and it should be noted that while both the lower and upper racks cover substantially the entire area of the washing chamber for maximum capacity, the arrangement of the top racks contributes greatly to the convenience of loading and unloading.

Another novel feature of great convenience is provided by the construction of the invention for guiding and storing the electric cord and the supply and drain hoses when the dishwasher is not in use. Thus instead of hanging the cord on the cabinet or having to force it into the cabinet under conditions tending to promote tangling and possible kinking, the invention provides a storage compartment for the cord and a guide mechanism which offer positive assurance against tangling and kinking, thus adding to the convenience of the user as well as providing a substantial safety factor. The compartment and guide arrangement for the hoses 7 and 71 similarly facilitate the use and contribute to the dependability of the dishwasher. The arrangement of the latch handle as described is also advantageous in the use of the dishwasher, particularly in preventing operation of the motor except when the cover is positively closed and latched while at the same time facilitating interruption of the washing cycle for addition of temporarily overlooked articles to be washed.

While the form of apparatus herein described constitutes a preferred embodiment of the invention, it is to be understood that the invention is not limited to this precise form of apparatus, and that changes may be made therein without departing from the scope of the invention which is defined in the appended claims.
